Earth-like planets, Antarctic sea voyages, 3D-printed body parts and a big buzz about bees - February was a huge month in science news. How well do you remember the discoveries of last month?<\p>

February was a bumper month in science news. Have you been paying attention? Put yourself to the test.

Researchers from Geoscience Australia are on board the RV Investigator’s latest trip to Antarctica. They filmed new underwater footage that revealed what?

CSIRO researchers developed a new low-carb diet. What is it good for managing?

Macropods (the kangaroo family) are predominantly foraging herbivores. The swamp wallaby (Wallabia bicolor) is considered to be no different, consuming mainly plants. However, a recent study out of The Nature Conservancy pointed to examples of the swamp wallaby eating what?

There was quite a buzz about some new research from a team of scientists from Queen Mary University in London last month. The study showed that bees have cognitive powers way beyond what we thought an insect could have. What clever trick were the bees able to achieve?

So 3D-printing body parts is a thing. We helped Melbourne-based company Anatomics create a replacement sternum for a patient in England. This is the second 3D-printed sternum we’re worked on, what made this one different?

A team of astronomers in the USA made a prediction about that, give or take a year, a pair of stars will merge and explode, becoming one of the brightest objects in the sky for a short period. In which year did they predict this event would occur?

Cathedral termites build huge mounds up to eight metres high in the Northern Territory, Western Australia and Queensland - representing some of the tallest non-human animal structures in the world (comparatively speaking). A paper published last month in the Royal Society journal Biology Letters looked at their evolutionary history. Where do the researchers think the termite’s ancestors originated?

One of the most internet-breaking discoveries of last month was NASA finding seven new earth-sized exoplanets around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of the planets orbit in the habitable zone around the star and all of them could have liquid water in the right conditions. Amazing, right? The question is, how long would it take for us to reach these planets with current technology?

Curtin University researchers recorded what unexpected animal singing in choruses at dawn and at dusk in Western Australia last month?

Carbon fibre - It’s far stronger than steel at just a fraction of steel’s weight. CSIRO and Deakin University researchers launched a new facility in Geelong that will revolutionise the manufacturing industry with what Australian first?

A new paper by New Zealand geoscience agency, GNS Science, discovered that several islands, notably New Zealand and New Caledonia, are connected by submerged continental crust across a large area of Earth’s surface. What did they call the new continent?
